If you are looking for leather, I am really happy with TT Gunleather. His products are top notch and his delivery schedule is accurate.

I have a mag carrier from him for my CCW rig. I'll have to see what his lead times are looking like because I really like the mag carrier. Wish I could get a milt sparks but the lead time is redonkulous.
